How Risky Are Social Networking Sites for Kids

by Dr Shock in Dr Shock MD PhD

This article discussed in this post, isn’t recent but the conclusion is very nuanced which isn’t always the case with publications especially in news media about social networking and kids or adolescents. Seems that politicians are advocating measures to restrict social networking for children in order to prevent assumed online sexual exploitation and Internet harassment.
Broad [...]

Latest 'Coping With Cancer' publications

by Drew Rosielle MD in Pallimed: a Hospice & Palliative Medicine Blog

A few analyses from the Coping With Cancer Study have been published recently, all in the Journal of Clinical Oncology. We've published extensively about the CWCS (see here for more). Briefly, it was a prospective, US multi-institutional study of several hundred advanced cancer patients (& their family caregivers) which measured at baseline, among many things, characteristics of patient coping, communication with clinicians, and care preferences. Patients were followed through death, and ........ Read more »

2/3 of the truth

by Drew Rosielle MD in Pallimed: a Hospice & Palliative Medicine Blog

NEJM has an editorial discussing withholding information from patients. It's a practical, casual discussion of 1) the fact that in real life we withhold information from patients all the time (e.g. don't go into all the details as they can be confusing, overwhelming, or superfluous), and 2) the fact that we decide all the time to withhold certain major pieces information out of a desire to protect the patient emotionally. It's the latter that is the real issue (e.g. not talking with a leuke........ Read more »

More on the M2 Channel Structure Controversy

by Nick Anthis in The Scientific Activist

Last year, I wrote about a scientific controversy over the structure of the influenza M2 proton channel, particularly over the protein's binding site for adamantane type anti-flu drugs. The Schnell/Chou model, based on solution NMR, had the drug binding to the outside of the channel, within the membrane (at a 4:1 drug:protein ratio). On the other hand, the Stouffer/DeGrado model had the drug binding inside the channel (1:1 ratio), based on X-ray crystallography studies.

A new study was recently........ Read more »

Cumulative Culture Evolved to Rapidly Coordinate Novel Behaviours

by Wintz in A Replicated Typo

In the deliberations over humanity and its perceived uniqueness, a link is frequently made between our ability to support a rich, diverse culture and the origin of complex human behaviour. Yet what is often overlooked in our view of these two, clearly connected phenomena is the thread that weaves them together: the ability to coordinate [...]... Read more »

Of Mice and Methamphetamine

Diabetes drug being tested for addiction.
It’s a mouthful: peroxisome proliferator activated receptor gamma (PPAR-gamma). 
Peroxisomes are specialized subunits inside cells that help metabolize various substances, including fatty acids and certain toxins. A blockbuster member of this drug family—Avandia—is a much disputed but immensely lucrative diabetes medicine that may cause heart failure.

The Good Jeans Hypothesis

by Wayne Hooke in The Psychology of Beauty

Just about every article I read on women’s preferences for sexual dimorphism in men points out that the data are consistent with the good genes hypothesis. There are a couple of technical variations of this hypothesis, but they all are based on the reasonably well-established connection between testosterone and impeded immune system functioning. The idea [...]... Read more »

Is that training diary doing anything?

by Lorimer Moseley in BodyInMind

One really cool aspect of using a software program like Recognise, is that you can keep tabs on whether or not patients actually do what we ask them to do.  This is an important issue because any treatment that involves home exercises or training depends on people doing it!  Historically, clinicians have used a training [...]...

Does Coenzyme Q10 Relieve Statin-Induced Muscle Pain?

by Scott in Science-Based Pharmacy

Editor’s Note:
Today’s guest post is from a pharmacist who blogs under the pseudonym Avicenna, who looks at the evidence supporting the use of Coenzyme Q10 to treat statin-related muscle pain.

My pharmacy stocks plenty of natural health products (NHPs) and ensuring they can be used safely is challenging, given the limited information available on safety, quality, [...]... Read more »

Of fairy rings and other mysteries

by steffi suhr in Science behind the scenes

I just came back up from our cellar, where I was looking through a couple of cardboard boxes that I hadn’t opened since we moved from Colorado. The boxes are full of research papers on benthic foraminifera, left over from my days of doing science. I ventured down there because a researcher from Sweden wants to have a reprint of one of my papers, and I don’t have an electronic file of it (I will after this).
Turns out the paper wasn’t in either of the two boxes, but in ........ Read more »

Psst!… Pass it on! Cortical communication via the thalamus

by Kevin Mitchell in Wiring the Brain

Many neuroscientists think of the thalamus – a compact structure lying right in the centre of the brain – simply as a relay station, where sensory information from the periphery converges and is then passed on to the cortex.  The cortex is thought to be the site of perception and cognition, with different cortical areas specialized to subserve different functions.  Communication between cortical areas can be mediated by axonal tracts running in the white matter of the cortex.  This leads ........

People with high risk factors for disability get more biomedical information

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

For a couple of years now, the focus of researchers on factors that identify ‘high risk’ of ongoing disability has turned from patients and onto providers. I’ve written before that health provider’s own beliefs about pain, particularly pain-related anxiety and avoidance, can change the advice they give. This can lead to less ‘reassurance’ about [...]...

How Many Children Need Mental Health Treatment and Get It?

by Child Psych in Child Psych

Photo by D Sharon Pruitt
There's more evidence that many children have a mental health disorder and not enough get help. The first representative survey of children in the United States found that 13% of children ages 8 to 15 had at least one psychiatric disorders during one year. The data comes from the National Health and Nutrition Examination Survey (NHANES), a collaboration between the National Institute of Mental Health (NIMH) and the National Center for Health Statistics of the Centers f........

Paper of the week: What ocean acidification means for the plankton

by Sarah Stephen in An ecological oratorio

It appears that we humans had taken oceans for granted for too long. A widely known fact is that most of what we discard makes its way to oceans. Oceans are sinks for all things including 1/3 of the carbon dioxide that has been released in the last 200 years. This has resulted in the acidification of the oceans. The science behind is that carbonic acid is formed when carbon dioxide dissolves in sea water. This raises the hydrogen ion concentration and bicarbonate ions, but limits carbonate ions.........

Physical Activity and Mental Health

by PhD Blogger in Exercise Psychology

Babyak (2000) examined the use of physical activity as a treatment for depression. Participants classified as clinically depressed were given, aerobic exercise, drugs or both as treatment. The exercise only group recovered as well as the other groups but had a lower relapse rate, perhaps caused by the participants feeling that they had a more active role in their treatment. The exercise group also a side effect of the participants getting fitter! There are many other studies associating par........ Read more »

House Finches, Disease, and Bird Feeders

by John Beetham in A DC Birding Blog

 House Finches at a Feeder Like humans, birds can be infected by various diseases, some of which can be quite contagious. Among feeder birds, House Finches are particularly susceptible to Mycoplasmal conjunctivitis. Avian conjunctivitis causes very noticeable changes to a bird's appearance and behavior. Infected birds appear to have swollen or crusty eyes. Becoming lethargic, they succumb more easily to starvation or predation.A new study examines behaviors that may encourage the spread of ........

Tipsy on multilingualism?!

by Ingrid Piller in Language on the Move

English-speaking countries have a poor track record when it comes to language learning. Educators in Australia, the UK and the USA regularly bemoan that fact and call for a change in language policy to strengthen the learning of languages other than English. One of their key arguments is economic: language learning is good for the [...]... Read more »
